KMC Controls SSS-1004 Sensor

For precise airflow monitoring in large-scale VAV terminal units and fan-powered boxes, the KMC Controls SSS-1004 differential pressure sensor provides the reliable velocity pressure data required for high-performance building automation. This differential pressure flow sensor features an insertion length of 7-21/32 inches (195 mm), making it specifically engineered for terminal box inlet diameters ranging from 10 to 14 inches. Utilizing three precise sensing points along the probe, the SSS-1004 averages velocity pressure across the duct cross-section to output an accurate "H" (high) and "L" (low) signal to your VAV controller.

The unit is constructed from durable ABS/polycarbonate and includes an integral mounting flange with a 1/4-inch foam gasket to prevent air bypass at the penetration point. Designed for standard field installations, it connects via 1/4-inch barbed nipples typically used with 3/8-inch OD polyethylene tubing. For veteran technicians balancing complex air loops, the SSS-1004 air flow sensor is a staple for maintaining calibrated CFM setpoints in variable air volume systems, ensuring the BACnet or Analog controller receives a clean, averaged signal even in turbulent inlet conditions.

Key Benefits

• Enhanced Accuracy: Features 3 sensing points for a more representative average of velocity pressure compared to single-point pitot tubes.
• HVACR Field Durability: Rugged ABS/Polycarbonate housing rated for operating temperatures between 40??F and 120??F.
• Simple Installation: Standard 7/8-inch duct cutout with an integral gasketed flange simplifies mounting on sheet metal ducts.
• Broad Compatibility: Seamlessly integrates with KMC CSC-3000, CSP-4000/5000, and BAC-7000 series controllers.

Common Questions

How do I determine the CFM from this sensor?
Airflow is calculated using the sensor?ÇÖs specific K-factor (3200 for the SSS-1004) multiplied by the square root of the differential pressure measured across the ports.

Can this sensor be used for static pressure?
While designed for differential velocity pressure, static pressure can be measured by utilizing a single port and rotating the probe 90 degrees from the airflow direction, though a dedicated static probe is recommended for permanent BAS sensing.

What tubing size is required for the SSS-1004?
The 1/4-inch barbed connections on this model are designed to fit 3/8-inch OD polyethylene tubing. If using 1/4-inch OD tubing, a barb union adapter is required.
